Page 7: Cleaning
Periodic cleaning of Follett’s ice machine system is required to ensure peak performance and delivery of clean, sanitary ice. The recommended cleaning procedures that follow should be performed at least as frequently as recommended and more often if environmental conditions dictate. - Page 8 § Do not use solvents, abrasive cleaners, metal scrapers or sharp objects to clean any part of the dispenser. SafeCLEAN Plus Solution: Follow the directions on the SafeCLEAN Plus packaging to mix 1 gal. (3.8 L) of Follett SafeCLEAN Plus solution. Use 100 F (38 C) water.

Page 9: Service
Service Ice machine Operation (all models) Follett’s ice machine consists of four distinct functional systems: § Harvesting system § Water system § Electrical control system § Refrigeration system These four systems work together to accomplish the production and harvesting of ice. A problem in any one of these systems will result in improper operation of the entire ice production cycle. -
Page 10: Water System
Water system The water level in the evaporator is controlled by a fill solenoid (Fig 1) and level detecting sensors. Water sensing rods (Fig. 2) extend down into the reservoir at the end of the evaporator assembly. The system works via electrical conductivity as follows: One of the longest probes is a common. -
Page 11: Electrical System
Electrical system ATTENTION! To prevent circuit breaker overload, wait 15 minutes before restarting this unit. This allows the compressor to equalize and the evaporator to thaw.

Green indicator lights generally represent “go”... - Page 12 A soft error can either be automatically reset should the condition rectify, or if power is cycled. Should an error occur, consult the troubleshooting guide in this manual or a Follett service technician.

Page 13: Electrical Control System Schematic
BLACK #69 Electrical control system operation The P425A/W, MCD425A/W_S and R425A/W wiring diagrams which follow illustrate the circuitry of Follett ice machines used with ice dispensers. Both normal operation of the ice machine (Stages 1–6) and non-normal diagnostic sequences showing torque-out (Stages 7–10) for use in troubleshooting ice machine problems are shown. - Page 14 Note: The operation stage descriptions that follow are based on the unit containing the split-phase gear motor. Normal operation – Stage 1 Power is supplied to L1 of the control board, the POWER LED light begins flashing. The ice level bin thermostat in the dispenser is closed and calling for ice, supplying contact closure to the control board.
- Page 15 Normal operation – Stage 2 When continuity is seen between B and C, the water valve de-energizes, the AUGER output (P4) comes on along with the MAKING ICE LED. The auger gearmotor’s start windings are energized through a current style start relay that is pulled in by the initial high current draw of the gearmotor.
- Page 16 Normal operation – Stage 4 One second (1 s) after the fan comes on, the COMPRESSOR output comes on. The compressor circuit uses both run and start capacitors along with a potential start relay. The start capacitor in energized through the normally closed contacts of the start relay.
- Page 17 Normal operation – Stage 6 Once the bin thermostat control opens, the LOW BIN LED goes out. The compressor and gear motor outputs turn off, the MAKING ICE LED goes out and the TIME DELAY LED comes on. . T.O.L. High Pressure Switch...
- Page 18 Normal operation – Stage 8 When the dwell time of 20 minutes has expired, the TIME DELAY LED goes off. If 5 seconds of ice has been dispensed and the SLEEP CYCLE LED (Symphony Plus only) is off, the ice machine will go through the normal start-up sequence when the bin level control signals the control board for ice.
- Page 19 Self-flushing (when enabled) At the completion of the 20 minute time delay, the machine checks for a cumulative one hour of ice making time since the last off-cycle flush. If the cumulative ice making time exceeds one hour, the machine will energize the drain valve P19 for 60 seconds to drain the evaporator.

- Page 21 High gearmotor amps – Stage 2 If the restart is successful the board will continue to monitor the current draw on P4 for 60 minutes looking for a second high amps (above 3A) occurrence. If the ice machine runs without problems for 60 minutes and no additional torque errors occur, the ice machine will continue normal operation.
- Page 22 Loss of water During operation, the water level cycles between the normal low (D) and normal high (C) water probes - the fill valve (P21) cycling on and off. If continuity is not detected between the common probe (B) and normal low (D) within 10 seconds, the LOW WATER and TIME DELAY LEDs will come on and the machine will shut down for the one hour time delay period.
- Page 23 High refrigerant pressure Should the refrigeration pressure rise above 425 psi, the high pressure switch contacts will open. The board sees the open circuit and the HIGH PRESSURE and TIME DELAY LEDs will come on, the machine shuts down. After the one hour time delay, the machine will attempt to restart.

Page 24: Refrigeration System (All Models)
Refrigeration system (all models) All service on refrigeration systems must be performed in accordance with all federal, state and local laws. It is the responsibility of the technician to ensure that these requirements are met. Recharging ice machine to other than factory specifications will void the warranty. - Page 25 R404A Refrigerant replacement requirements 1. Non-contaminated refrigerant removed from any Follett refrigeration system can be recycled and returned to the same system after completing repairs. Recycled refrigerant must be stored in a clean, approved storage container. If additional refrigerant is required, virgin or reclaimed refrigerant that meets ARI standard 700-88 must be used.
- Page 26 Evaporator disassembly Note: The upper bearing, lower bearing and auger assemblies must be replaced as assemblies. The bottom and top bearing assemblies cannot be field assembled to factory specifications. 1. Press CLEAN switch. Fig. 3 2. Wait for LOW WATER light to illuminate. 3.
- Page 27 6. Lower bottom bearing assembly into Fig. 5 evaporator mounting base. 7. While maintaining firm downward pressure on bottom bearing assembly, tighten hex head bolt with a 5/16 wrench. 8. Position evaporator over lower bearing assembly and align grooves with pins in bearing assembly.
